Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 32 points:

(5,8)(9,10)(11,13)(12,15)(14,16)(17,18,22,26)(19,27,28,31)(20,23,21,25)(24,29,32,30);(1,2)(3,5)(4,6)(7,8)(18,23)(20,21)(24,31)(25,26)(27,32)(29,30);(1,3)(2,5)(4,7)(6,8)(10,13)(11,16)(14,15)(17,19,22,28)(18,24,26,32)(20,30,21,29)(23,31,25,27);(2,6)(5,8)(19,28)(24,32)(27,31)(29,30)
